Transformer Resistance Testing
-
Weshine Electric Manufacturing Co., Ltd
Transformer insulation resistance deterioration is one of the most common causes of transformer failure: a failing transformer is a costly replacement in an electrical system with the potential for a long downtime. If you fail to maintain your transformer with regular insulation resistance testing (as can be carried out by the WESHINE Transformer Ohmmeter (VS-3110 series) of transformer test equipment) then it’s likely to fail before reaching its maximum operating life.

Single-Phase Transformer Winding Resistance Meters
RMO-TW Series
-
RMO-TW series is perfect for winding resistance measurements of inductive objects. It is ideal for testing transformer windings (power transformers, distribution, autotransformers) and for on-load tap changer verification. In addition, any RMO-TW transformer ohmmeter & tap changer analyzer can also perform transformer demagnetization.The series contains 4 models, with maximal test currents from 10 A (RMO10TW) to 50 A (RMO50TW). They are fitted in a portable and lightweight metal housing.All transformer ohmmeters from RMO-TW series generate a true DC ripple-free current with automatically regulated measurement and discharging circuit. The injection of current and discharge of energy from the test object are automatically regulated.Three independent channels enable testing of three windings in series. Consequently, this enables measurements of winding resistance in every tap position of an on-load tap changer without discharging between the tests.DV-Win software enables control and observation of the test process, as well as saving and analyzing the results on a PC. It provides a test report, arranged in a selectable form as an Excel spreadsheet, PDF, Word, or ASCII format. Additionally, DV-Win measures and calculates the OLTC transition time, the ripple and the winding resistance for each tap changing operation. The software can also perform the calculations necessary for the “Heat Run” test. Finally, a user can export all results in the form of a report.

AC Test Transformer
-
Shanghai Guantu Technology Co., Ltd.
How the AC test transformer prevents the overvoltage generated by the frequency conversion series resonance test device is a relatively simple problem, but the overvoltage caused by voltage fluctuation is difficult to appear when the overvoltage protection is set. Generally, the overvoltage of the frequency conversion series resonance test device will appear in the frequency sweep stage of the instrument, that is, in the process of finding the resonance point. Those who have used it know that in the process of finding the resonance point of the frequency conversion series resonance test device, the voltage and frequency have a parabola-like linear relationship. By default, the system finds the high voltage, that is, the apex of the parabola as the resonance point.

Fast Mobility Particle Sizer (FMPS)
3091
-
Monitor the size distribution of quickly-changing aerosols. Whether outdoors or indoors, some aerosol populations change too rapidly for standard aerosol size measurement techniques. The Fast Mobility Particle Sizer (FMPS) 3091 measures particles in the range from 5.6 to 560 nm with 1 Hz time resolution. This combination of two-decade size distribution and 1 Hz time resolution makes the FMPS a very valuable tool for monitoring particle exposures in rapidly changing environments. Suitable for measuring near street canyons, airports, or mines, as well as emissions from processes such as incineration, cigarettes, or printers.

Three-Phase Transformer Winding Resistance Meters
TWA Advanced Series
-
TWA Advanced series is the latest DV Power solution for three-phase transformer winding resistance measurement and tap changer analysis. They are capable of testing six transformer windings with a single cable connection, as well as three-phase automatic transformer demagnetization. It has the option of the automated test mode, where the instrument operates the tap changer without operator input (minimizing the risk of human error) and records winding resistance results based on pre-selected stabilization criteria.The unique DVtest method of tap changer analysis enables checking the moving contacts of on-load tap changers during the transition, measuring the transition time, detecting open circuits, and many other types of faults. It is performed with 0.1 ms sampling rate, together with the measurement of tap changer motor current which detects motor and mechanical issues. A special proprietary algorithm is used for testing tap changers connected through a built-in series (booster) transformer. The DVtest can be performed either on one phase or simultaneously on three phases. It can also be performed together with the winding resistance test in all tap positions.A unique advantage of TWA Advanced instruments is the capability of simultaneously testing the winding resistance of all three phases of a three-phase transformer connected in a YN configuration. This can significantly speed up the testing– for example, it enables the operator to perform 33 measurements instead of 99 on a tap changer with 33 tap positions.TWA500 is equipped with a large 10.1” graphical touch-screen display, while TWA400 has a 7” graphical touch-screen display. Besides making the interface much more user-friendly compared to older winding ohmmeters, it also enables certain test options that were previously available only with DV-Win software. The most important among them are DVtest, tap changer motor current measurement, “Heat Run” test, test templates, and automatic test mode.
